Lea Michele attends memorial for Cory with Glee co-stars

The heartbroken actress, 26, whose boyfriend of 14 months was found dead in his hotel room in Vancouver, Canada, on July 13, after he overdosed on heroin and alcohol, joined her 'Glee' co-stars and the show's creator Ryan Murphy at a private service to remember Cory, 31, who battled addiction since he was a teenager.

A statement from 20th Century Fox Television said that Lea attended the memorial "along with colleagues from the network and studio, to share memories and music in an emotional celebration of the life of Cory Monteith.

"We thank the public for their continued outpouring of love and support as we grieve our friend and colleague during this difficult time."

Lea and Cory were previously reported to have been planning to move in together after he returned from Vancouver and she returned from vacation in Mexico.

A source told Us Weekly magazine: "Lea and Cory were planning on moving in together after he got back from Vancouver. [They] weren't talking engagement or marriage yet, but it was heading that way.

"The first step was that Cory was going to move in [to Lea's Los Angeles home] completely. He was already there all the time."

The source added: "She [Lea] didn't know what [he was planning] but she thought it could be a party and possibly a trip somewhere."
